“…All antennas are pointed at the ChangE-3 lunar lander (CE3) coordinates at 44.12 • N, 19.51 • W [23] at the Mare Imbrium lunar region, taking into account the signal round-trip travel time. The Chinese radar antenna at station Kashi (Ks) [21] illuminates the moon with a continuous wave (CW) signal at a frequency of 7209.125 MHz in left-hand circular polarization. The carrier frequency is not changed over time and the transmitter power reaches 200 W. The signal reflected from the moon is received with the 40-m Kunming (Km) and 13.2-m Zelenchukskaya (Zv) radio telescopes of the CVN and the Quasar VLBI network in left-and right-hand circular polarizations simultaneously, i.e., in the same (SC) and opposite (OC) circular polarizations as that of the transmitted wave.…”

Earth-based radar astronomical observations provide information on surface characteristics, orbits, and rotations for a wide variety of solar system objects. Based on compound radio telescopes, both the Chinese VLBI (Very Long Baseline Interferometry) network (CVN) and the Russian VLBI network (Quasar), in cooperation with the Chinese radar transmitters, we present the current ground radar astronomical observations of the moon. The spectrum of the reflected radio signals was obtained and the Doppler frequency shift in bi-static radar mode was measured. Radar albedo of the observed region and power ratios of the reflected signals with left- and right-hand circular polarizations were determined, allowing us to study the radar reflectivity and near-surface wavelength-scale roughness of the moon. Future developments on radar astronomy are also discussed in the paper.

“…There are several fully steerable dishes equipped with powerful X-band transmitters in China, which are used for deep spacecraft communications [21,22]. The close collaboration of radar transmitters with the CVN gives us the opportunity to apply the VLBI technique in order to receive and analyze echo signals.…”

“…Radio telescopes at Jiamusi and Kashi stations of the Chinese Deep Space Network with 66 m and 35 m antennas [2] regulary transmit the signal to CE-3. Reradiated signal from the transponder is recorded simultaneously by the 32 m radio telescopes (RT-32) at Svetloe, Zelenchukskaya and Badary observatories [3], as well as by the radio telescopes at the Seshan, Kunming and Urumqi observatories that are part of the National Astronomical Observatories of the Chinese Academy of Sciences (NAOC).…”

Since 2017, the Institute of Applied Astronomy of the Russian Academy of Sciences in cooperation with the National Astronomical Observatories of the Chinese Academy of Sciences has been conducting observations of the Chang’E-3 lander carrier wave signal. The paper presents the features of observation scheduling and results of data processing. High-precision phase radar measurements have been obtained with an instrumental error of 1–2 mm. The deviation of residuals in model calculations does not exceed ± 1 cm. The estimates of CE-3 lander position have been obtained with an accuracy of 0.5’’, 7.4 m and 3.2 m in celenocentric cylindrical longitude, Px and Py coordinates, respectively.
